Not me personally. Arnd is the one mostly involved in dropping
support of obsolete hardware from the kernel.

I am copying Arnd, the OMAP1 Linux kernel maintainers, PXA2 maintainers,
and the Linux omap mailing list for input. Sorry for the noise for those
who don't care, but I think it is useful to have your voices heard.
Personally I think it very unlikely that anyone is using the latest Linux
kernel on any of the affected machines, but I may be wrong.
